3.
Add fluid as necessary.
4.
Drain and replace hydraulic fluid:
In a humid environment, drain and replace two quarts (.95 liters) of fluid every six
months
If humidity is not a problem, drain and replace one gallon (3.8 liters) of fluid every
year to prevent fluid wear.
NOTE:
This will drain any accumulated water and help prevent pump failure due to
water ingestion. It also will prevent excessive fluid wear and allow the fluid to main-
tain its hot end performance.
5.
Replace the hydraulic system cartridge filter every 500 hours of operation.
6.
Inspect and clean the hydraulic pump motor brushes every 750 hours of operation.
Replace the brushes if they worn to a length of 1/4” (6mm) or shorter.
CAUTION!
Do not operate the hydraulic system if the pump motor
brushes are worn shorter than 1/4” (6mm). Damage to the pump motor
may result.
7.
Periodically check all hydraulic lines and fitting as needed. Replace as necessary.
